87af0d1e1b net/mlx5: concentrate all device configurations
Move all device configure to be performed by mlx5_os_cap_config()
function instead of the spawn function.
In addition move all relevant fields from mlx5_dev_config structure to
mlx5_dev_cap.

151cbe3aab net/mlx5: separate Rx function declarations to another file
The mlx5_rxtx.c file contains a lot of Tx burst functions, each of those
is performance-optimized for the specific set of requested offloads.
These ones are generated on the basis of the template function and it
takes significant time to compile, just due to a large number of giant
functions generated in the same file and this compilation is not being
done in parallel with using multithreading.

Therefore we can split the mlx5_rxtx.c file into several separate files
to allow different functions to be compiled simultaneously.
In this patch, we separate Rx function declarations to different header
file in preparation for removing them from the source file and as an
optional preparation step for further consolidation of Rx burst
functions.

9d60f54569 common/mlx5: remove inclusion of Verbs header files
Several source files include Verbs header files as in (1). These source
files will not compile under non-Linux operating systems. This commit
removes this inclusion in two cases:

Case 1: There is no usage of ibv_* or mlx5dv_* symbols in the source
file so the inclusion in (1) can be safely removed.

Case 2: Verbs symbols are used. Please note the inclusion in (1) already
appears in file linux/mlx5_glue.h (which represents the interface
to the rdma-core library). Therefore, replace (1) in the source file
with (2).  Under non-Linux operating systems - file mlx5_glue.h will not
include (1).

(1)
 #include <infiniband/verbs.h>
 #include <infiniband/mlx5dv.h>

(2)

8e46d4e18f common/mlx5: improve assert control
Use the MLX5_ASSERT macros instead of the standard assert clause.
Depends on the RTE_LIBRTE_MLX5_DEBUG configuration option to define it.
If RTE_LIBRTE_MLX5_DEBUG is enabled MLX5_ASSERT is equal to RTE_VERIFY
to bypass the global CONFIG_RTE_ENABLE_ASSERT option.
If RTE_LIBRTE_MLX5_DEBUG is disabled, the global CONFIG_RTE_ENABLE_ASSERT
can still make this assert active by calling RTE_VERIFY inside RTE_ASSERT.

Some devices may not support or fail setting VLAN offload
configuration based on dynamic circumstances so the

the caller can determine success or not.

rte_eth_dev_set_vlan_offload is updated to return the
value provided by the vector when called along with restoring
the original offload configs on failure.

Existing vlan_offload_set_t vectors are modified to return
an int.  Majority of cases return 0 but a few that actually
can fail now return their failure codes.

Finally, a vlan_offload_set_t vector is added to virtio
to facilitate dynamically turning VLAN strip on or off.

70d32d3afe net/mlx5: fix removing VLAN filter
memmove was moving bytes as the number of elements next to i, while it
should move the number of elements multiplied by the size of each element.

to implement data path operation bypassing Verbs. Update the minimum
version requirement to MLNX_OFED >= 3.3 and clean up compatibility checks
for previous releases.

6a707608dc net/mlx5: fix Rx VLAN stripping capability check
A hardware capability check is missing before enabling RX VLAN stripping
during queue setup.

Also, while dev_conf.rxmode.hw_vlan_strip is currently a single bit that
can be stored in priv->hw_vlan_strip directly, it should be interpreted as
a boolean value for safety.

ecc1c29df8 mlx5: refactor Rx code for the new verbs RSS API
The new Verbs RSS API is lower-level than the previous one and much more
flexible but requires RX queues to use Work Queues (WQs) internally instead
of Queue Pairs (QPs), which are grouped in an indirection table used by a
new kind of hash RX QPs.

Hash RX QPs and the indirection table together replace the parent RSS QP
while WQs are mostly similar to child QPs.

RSS hash key is not configurable yet.

Summary of changes:

- Individual DPDK RX queues do not store flow properties anymore, this info
  is now part of the hash RX queues.
- All functions affecting the parent queue when RSS is enabled or the basic
  queues otherwise are modified to affect hash RX queues instead.
- Hash RX queues are also used when a single DPDK RX queue is configured (no
  RSS) to remove that special case.
- Hash RX queues and indirection table are created/destroyed when device
  is started/stopped in addition to create/destroy flows.
- Contrary to QPs, WQs are moved to the "ready" state before posting RX
  buffers, otherwise they are ignored.
- Resource domain information is added to WQs for better performance.
- CQs are not resized anymore when switching between non-SG and SG modes as
  it does not work correctly with WQs. Use the largest possible size
  instead, since CQ size does not have to be the same as the number of
  elements in the RX queue. This also applies to the maximum number of
  outstanding WRs in a WQ (max_recv_wr).
